Data compression is the compacting of info by lowering the number of bits that are stored or transmitted. Consequently, the compressed data needs much less disk space than the initial one, so extra content could be stored on the same amount of space. You can find many different compression algorithms which function in different ways and with a number of them only the redundant bits are deleted, which means that once the info is uncompressed, there's no decrease in quality. Others remove unneeded bits, but uncompressing the data afterwards will result in reduced quality compared to the original. Compressing and uncompressing content requires a large amount of system resources, in particular CPU processing time, therefore any hosting platform that employs compression in real time needs to have adequate power to support that feature. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of keeping the whole code.

Data Compression in Website Hosting

The ZFS file system that runs on our cloud web hosting platform uses a compression algorithm identified as LZ4. The aforementioned is substantially faster and better than any other algorithm you'll find, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data quite well and it does that quickly, we can generate several backups of all the content stored in the website hosting accounts on our servers every day. Both your content and its backups will take less space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the web hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

In case you host your websites in a semi-dedicated server account with our company, you will be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud web hosting platform. What separates LZ4 from all other algorithms out there is that it has a better compression ratio and it is way quicker, in particular when it comes to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard drive, so your Internet sites will perform faster. The higher speed is at the expense of using a lot of CPU processing time, which is not a problem for our platform as it consists of a large number of clusters working together. Besides the better performance, you will also have multiple daily backups at your disposal, so you will be able to recover any deleted content with just a few clicks. The backups are available for a whole month and we can afford to keep them as they take significantly less space than traditional backups.
